I have an unattached metal garage and was wondering what I have to do to get phone and wifi there. We have Xfinity in the house but the signal isn't available inside the garage. Any ideas are apreciated.
FWIW, even if the WiFi signal is strong enough for the internet service, you can't get their phone service in there without a hardwired phone cord from the gateway device going in to there.
Hello @drmopar1. You can run an Ethernet and telephone cord from your in-home wireless gateway, through conduit to the garage. I would urge extreme caution and suggest hiring an independent contractor to do the job to ensure the wiring is safely protected and conduit is laid in a safe, weatherproof manner. Once in the garage you can setup a standalone wireless router to create your own WiFi network. This just an idea, not a service Comcast installers could perform.
Please let us know if you have any further questions.
OP. FYI. If you run a stand-alone router in the garage from an ethernet cable that is connected to a combination gateway device in the house, and the gateway is not in *bridge mode*, you are cascading 2 routing devices which results in an undesirable "double NAT" condition on your home network.
Google "double NAT" for info about it's potential pitfalls.
You should connect a WiFi repeater / extender in the garage for your WiFi needs, not a stand-alone router.
